当我用下面的code片段通过DefaultHttpServerConnection属性为handle（）方法，我没有得到这个异​​常：

When I passed the DefaultHttpServerConnection attribute to the handle() method using the following code snippet, I did not get this exception:

在的WorkerThread类，使用下面的code传递DefaultHttpServerConnection连接对象：

In the WorkerThread class, pass the DefaultHttpServerConnection connection object using the following code:

HttpContext context = new BasicHttpContext(null);
context.setAttribute("XXX",this.conn);

在手柄（）方法，用得到的连接对象，

In the handle() method, get the connection object using,

(DefaultHttpServerConnection)context.getAttribute("XXX");

希望它可以帮助别人！
